DRAFT APPARATUS FOR STOVES.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed June 22, 1908. Serial No. 139,660.

draft apparatus as mentioned, which may be effectually operated with ease.

A further object of my invention is to provide a draft device as mentioned, which may be readily attached to the ordinary stovepipe, and one which will be strong, durable and simple of construction, hence of low cost to manufacture.

Other objects will appear hereinafter.

With these objects in view, my invention consists generally in a fan wheel fixed to a verticall dis )osed shaft, said shaft bein rotatably mounted in a suitable frame, and in means on said frame for securely attaching the same to the inside of a stove-pipe.

My invention further consists in a beveled gear fixed to a horizontal shaft, said shaft being suitably mounted in brackets on said fan shaft supporting frame, the teeth of said beveled gear being adapted to mesh with the teeth of a beveled pinion fixed to the upper end of said fan wheel shaft.

My invention further consists in means at the outer end of said horizontal shaft for manually rotating said shaft and hence, said fan wheel.

My invention further consists in certain details of construction and arrangements of parts all as will be fully described hereinafter.

My invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which,

Figure 1 is a side elevation of my draft apparatus attached, the stove-pipe being broken away so as to expose the same, and Fig. 2 is a top plan View thereof,

Referring now to the drawings, 1 indicates a circular metal band, the outside diameter of said circular band 1 and having its ends 3 secured preferably by a rivet 1 to the band 1 as shown in the drawings, is a preferably rectangular frame 5 Vertically disposed and mounted in suitable bearings through sub stantially the center of the frame 1, is a shaft 6. Suitably fixed to the upper end 7 of the shaft 6 is a beveled pinion 8, the underface 9 of the lower portion 10 of said pinion 8 resting upon the upper face 5 of the frame 5. Suitably fixed to the lower end 11 of the shaft 6 is an ordinary fan wheel 12, the diameter of said fan wheel being slightly less than the diameter of the stove-pipe 2. lrtiveted or otherwise secured, to said frame 5 upon the upper surface 5 thereof, are brackets 13 and 3. Horizontally disposed and mounted in suitable bearings in the brackets 13 and 13 is a shaft 1 1, the outer end 15 of said shaft projecting outside of the stove-pipe 2 as shown in the drawing. Suitably fixed to the inner end portion 16 of said shaft 14 is a beveled gear 17 which meshes with said beveled pinion 8 on the fan wheel shaft 6. The bracket 13 against which rests the beveled gear 17, is so positioned on the frame 5 as to keep said beveled gear in constant mesh with the beveled pinion 8. Detachably secured, preferably by screws or rivets 18 to the outer end 15 of the shaft 1 1, is a suitable handle portion 19.

In attaching my device to a stove-pipe, the stove-pipe is apertured as at 20 to receive the end portion 15 0f the shaft 14, the handle portion 19 being detached to facilitate so doing. When the device is in position the band 1 is secured preferably by the rivet 21 to the inside of the stove-pi e. The handle 19 is then attached as stater to the shaft 14 and the device is ready for use.

aving described my invention what I claim as new, and desire to secure by Letters Patent, is:

The combination with an ordinary stovepipe, of a circular metal band secured. to the inside thereof, a rectangular frame secured to said circular band and comprising a pair of horizontal transverse bars and a pair of vertical end bars, a vertically disposed shaft mounted centrally in said frame and having hearings in both of said transverse bars, a fan wheel and a beveled pinion fixed to said of which, is substantially the same as the inshaft the former below said frame and the side diameter of the ordinary circular sheet metal pipe Extending through the center latter above the same, a horizontally disposed shaft, brackets on the upper bar of said frame and supporting said horizontal name to this specification in the presence of sgaft, a beveled gigear fixed tto said gorizoital two subscribing witnesses. s aft, said eve ed ear ein a a te to w mesh with said bevel ed pinion and crank ALOIS KAMPE 5 on the outer end-of said horizontal shaft, sub- Witnesses: stantially as described.
